You can use zgrep also

Code:
/user/ahamed> zgrep -o "[^ ]*@[^ ]*" http.log.20110808.gz 
igchung@abc.com
sastria9@abc.com
sastria9@abc.com
sastria9@abc.com
pntcdor1@abc.com
pntcdor1@abc.com
pntcdor1@abc.com
visnet@abc.com
visnet@abc.com
visnet@abc.com
visnet@abc.com
animan86@abc.com

Using sed

Code:
gzip -dc http.log.20110801.gz | sed 's/.*] \(.*@.*com\) .*/\1/g' | sort | uniq

Ahamed

Try this:

Code:
gzip -dc http.log.20110808.gz | nawk ' /@/ { sub("^.*] ",""); sub(" .*", ""); if(!($0 in E)) print; E[$0]} ' > uniqueemail.out

user/ris1@yiris.net/INBOX 
user/ris2@giris.net/INBOX 
user/ris3@iris.net/INBOX 
user/ris4@hiris.net/INBOX 
user/str1@eamyx.com/INBOX 
user/str2@amyx.com/INBOX
